Hello all!
I use Autoit for a while, already made some automation for a TV station's master control room with it. I made a UDF to easily work with PAL timecode and time with milliseconds, convert, add or subtract them. Feel free to use it if you want something like this

And the example script:
#include<_PAL_TC_Calc.au3>
$palTC1 = "00:01:12.20"
$palTC2 = "23:59:50.02"
$msTC1 = "00:01:12.800"
$msTC2 = "23:59:50.120"
MsgBox(0, "1", _tcAdd($palTC1, $palTC2)); Adds $palTC1 to $palTC2, turns hour back to 0 after 23, returns PAL TC format
MsgBox(0, "2", _tcAdd($palTC1, $palTC2, "M")); Adds $palTC1 to $palTC2, turns hour back to 0 after 23, returns time with milliseconds format
MsgBox(0, "3", _tcAdd($palTC1, $palTC2, "M", 0)); Adds $palTC1 to $palTC2, hours can be infinite, returns time with milliseconds format
MsgBox(0, "4", _tcAdd($msTC1, $msTC2)); Adds $palTC1 to $palTC2, turns hour back to 0 after 23, returns PAL TC format
MsgBox(0, "5", _tcAdd($msTC1, $msTC2, "M")); Adds $palTC1 to $palTC2, turns hour back to 0 after 23, returns time with milliseconds format
MsgBox(0, "6", _tcAdd($msTC1, $msTC2, "M", 0)); Adds $palTC1 to $palTC2, hours can be infinite, returns time with milliseconds format
MsgBox(0, "7", _tcSub($palTC2, $palTC1)); Subtract $palTC1 from $palTC2, returns PAL TC format
MsgBox(0, "8", _tcSub($palTC2, $palTC1, "M")); Subtract $palTC1 from $palTC2, time with milliseconds format
MsgBox(0, "9", _tcSub($msTC1, $msTC2)); Subtract $palTC1 from $palTC2, returns PAL TC format - when hits zero, counts back from 24:00:00.00
MsgBox(0, "10", _tcSub($msTC1, $msTC2, "M")); Subtract $palTC1 from $palTC2, time with milliseconds format - when hits zero, counts back from 24:00:00.000
MsgBox(0, "11", _tcFormatChange($palTC2)); Convert PAL TC to time with milliseconds and back
MsgBox(0, "12", _tcFormatChange($msTC2)); Convert PAL TC to time with milliseconds and back
